Though he disagreed earlier when Stuart told him to lock the door, he still locked it. With nothing else to do he went to the gym room where he worked out until he was tired and hungry and his muscles sore from all the training. He took a bath again to wash off all the sweat and sat in the tub for a long time to relax his muscles.
Even though he wasn't in the restaurant, he worked at home, checking up on all his restaurants all over the world and making sure to confirm that they were in good conditions. As simple and as easy as it seemed, being a professional chef was difficult and stressful, not to mention he owned several restaurants which he had to maintain. A little mistake in the running of his restaurants could cause him a lot and ruin everything he had worked hard for all through his years.
